Some of 2014's most vocal artists—including Ariel Pink, St. Vincent, Perfume Genius, Pussy Riot, and Mark Kozelek—offer insight on topics like cultural appropriation, female empowerment, the pitfalls of the Internet, and what happens when we die.

Photographers Tom Spray, Kristina Pedersen, and Matt Lief Anderson capture moments with Chvrches, St. Vincent, Belle & Sebastian, James Blake, Four Tet, and more at this year's Pitchfork Music Festival Paris at Grande Halle de la Villette.
